Security workflow
PlannedFind design mistakes while changes are still cheap.
Threat modeling is a planned Winfunc workflow for turning a design into a structured view of assets, trust boundaries, failure cases, mitigations, and focused questions for deeper investigation.

The problem
Security work should end in a decision, not another queue.
Architecture choices create security assumptions long before a scanner has code to inspect. Teams need a practical way to review assets, actors, data flows, and trust boundaries while a design can still change.
WorkflowDesign context → threats and assumptions → mitigation plan
How it works
From scope to an engineering decision.
Bring a design document, system diagram, key actors, sensitive assets, expected data flows, and the feature decisions that are still open.
- 01Scope
Map actors, valuable assets, data flows, and trust boundaries
- 02Investigate
Review failure cases and the security assumptions behind the design
- 03Investigate
Prioritize credible threats and practical mitigations
- 04Review
Turn unresolved assumptions into code or hypothesis investigations
Review-ready output
What your team gets.
Prioritized threats and failure cases
Mitigation options and open questions
Built for handoff
Evidence your team can inspect.
Keep the reviewed scope, supporting evidence, uncertainty, and next action together so security and engineering can make the same decision from the same context.
Measure the workflow
Track design issues resolved before implementation, mitigation completion, investigation questions closed, and security-related rework per feature.
An architecture and trust-boundary map
A prioritized set of threats and failure cases
Security assumptions that need validation
Mitigation options with their rationale and owners
Focused investigation questions for implementation review
Why it matters
Surface important design concerns earlier and reduce expensive security rework late in delivery.
Scope & limits
Planned. The model reflects supplied design context; it does not prove that an implementation is secure.
